AdipoGen ANTS
Chemical. CAS 5398-34-5. Formula C10H7NNa2O9S3. Molecular Weight 427.34. ANTS is a highly negatively charged dye with an amino group that can be coupled to an aldehyde or ketone group to form an unstable Schiff base. The Schiff base is usually chemically reduced by sodium borohydride NaBH4 or sodium cyanoborohydride NaBCNH3 to form a stable linkage. This labeling technique has been widely used for the labeling and subsequent sequencing of oligosaccharides and glycoproteins. The negative charges of the dye facilitate the electrophoretic separation of the degradation products of carbohydrate polymers. The polyanionic dye ANTS is used together with the fluorescent cationic quencher DPX for membrane fusion studies or permeability assays. The mixture of ANTS-DPX is minimally fluorescent initially, but becomes increasingly more fluorescent upon dilution i.e. membrane fusion or leakage. ANTS also is used as a neuronal tracer.
PLANT CELL TECHNOLOGY PLANT PRESERVATIVE MIXTURE PPM
Plant Preservative Mixture (PPM) 100 Ml. Plant Preservative Mixture (PPM), is a broad-spectrum biocide/fungicide for plant tissue culture. PPM™ is the ultimate solution to the never-ending struggle against microbial airborne, waterborne and endogenous contamination. PPM™ is a heat stable preservative/biocide which can be used to effectively prevent or reduces microbial contamination in plant tissue culture. At optimum doses, PPM™, which stands for Plant Preservative Mixture™, is an extremely effective reservative/Biocide, yet does not impair in vitro seed germination, callus proliferation and callus regeneration.Despite the most stringent use of sterile techniques, the contamination of plant cell and plant tissue cultures remain a persistent problem that can result in losses ranging from small number of cultures to the loss of whole batches.PPM™ prevents the germination of both bacteria and fungi spores. It is heat stable and therefore can be autoclaved with the media.
